In modern mining transportation systems, mining trucks undertake extremely high-intensity transportation tasks. Faced with loads often reaching hundreds of tons and extremely complex working conditions, the wheel rim, as a core load-bearing component connecting the tire and the entire vehicle, directly determines the safety, stability, and operational efficiency of the entire vehicle.
In this critical area, HYWG leverages over 30 years of manufacturing expertise and technological accumulation to continuously provide highly reliable rim solutions to mining customers worldwide.
I. Core Requirements for Mining Truck Rims
1. Ultra-high strength and load-bearing capacity
Mining trucks operate under high impact and heavy loads for extended periods of continuous operation , which requires wheel rims to possess excellent structural strength , fatigue resistance , and deformation resistance .
HYWG's strong manufacturing and R&D capabilities can meet the stringent requirements of mining trucks . The factory has advanced automated welding production lines , high-precision rolling and forming processes , and a strict quality inspection system to ensure that every set of wheel rims has high consistency , high reliability , and a long service life .
for extreme mining conditions, HYWG rims feature a reinforced structural design (impact resistance) , the use of high-strength steel (crack resistance) , and optimized locking ring and sealing structures (enhanced safety) . They maintain stable operation even under high temperatures, high loads, and complex road conditions.
2. Split-type structural design (3PC / 5PC)
HYWG's mining rims typically employ a multi-piece structure , which facilitates tire installation and removal , improves on-site maintenance efficiency , and reduces downtime .
II. Advantages of HYWG Mining Rim Solutions
HYWG offers a variety of mining rim specifications, covering mainstream mining trucks and meeting the diverse needs of mining trucks of different tonnages. Products are widely used in: open-pit coal mines , metal mines , and stone quarries .
HYWG serves multiple markets globally and is an original equipment manufacturer (OEM) rim supplier in China for well-known brands such as Volvo, Caterpillar, Liebherr, and John Deere . With mature OEM experience , after-sales support system , and fast delivery capabilities , HYWG is a trusted partner for OTR users worldwide .
HYWG provides 13.00-33/2.5 rims for CAT's classic rigid mining dump truck, the Caterpillar 772.
For high-intensity transportation and complex road conditions , HYWG offers a 13.00-33/2.5 mining rim solution that achieves efficient matching with vehicle performance.
The 13.00-33/2.5 rim is a 5PC structure rim for TL tires, commonly used in rigid dump trucks. We are the original rim supplier for Volvo, Caterpillar, Liebherr, John Deere, and Doosan in China.
Common operating environments for CAT 772 wheels include open-pit mines (high impact from crushed rock) , quarries (high wear conditions) , and short-to-medium distance, high-frequency transportation . These complex operating conditions require wheel rims to have high impact resistance , long-cycle fatigue resistance , and highly stable sealing performance .
The 13.00-33/2.5 wheel rim features a compact design that provides stable tire support , optimizes stress distribution , and reduces localized stress concentration .
In medium-sized mining truck applications, this configuration can reduce tire procurement costs , minimize unnecessary over-specification configurations , and improve overall cost-effectiveness . It is ideal for cost-sensitive mining projects .
HYWG uses high-quality steel produced in-house and an optimized cross-section design to effectively improve impact resistance , prevent rim deformation and cracking , and extend service life .
HYWG possesses the capability to independently produce rim-grade steel, allowing it to better determine the safety limits, consistency, and long-term reliability of rims from the source. This results in products that are superior to ordinary standard rims in terms of concentricity, fatigue resistance, weld strength, and service life. High-strength, high-quality steel ensures that the rims exhibit excellent fatigue and impact resistance.
It possesses a complete industrial chain production from steel to finished wheel rims, including steel rolling, mold design, high-precision forming, automated welding, surface treatment, and finished product inspection. This "one-stop" production model ensures that all products meet uniform high standards, truly realizing full-chain manufacturing and quality control of wheel rims.
